描述了早泥盆世Alken an der Mosel的节肢动物轨迹，归属于遗迹种Palmichnum pottsae，并归属于从该组合中已知的中等大小的常翅目昆虫。动物学和沉积学证据表明，几种类似大小的动物同时爬向或远离横跨潮间带下部的海岸线，那里的轨道保存条件最有利。与现代马蹄蟹的比较表明，这种同步行为可能是等翅目动物生殖周期的一部分，支持了之前提出的“质量-蜕皮-配偶”假说。
Arthropod trackways from the Early Devonian of Alken an der Mosel are described, assigned to the ichnospecies Palmichnium pottsae and attributed to medium-sized eurypterids known from the assemblage. Ichnological and sedimentological evidence suggests that several similarly sized animals simultaneously crawled towards, or away from, the shoreline traversing the lower intertidal zone, where conditions for trackway preservation were most favourable. Comparison with modern horseshoe crabs suggests that this synchronized behaviour may have been part of the reproductive cycle of eurypterids, supporting the previously formulated ‘mass-moult-mate’ hypothesis.
